Compared to 2 - 3 years back today's eco-system around IT Operations has changed significantly, The definitive responsibility line between infrastructure administrators and developers has been blurring continuously. We have experienced that developers want to experience same level of ease as its publicly available in form of commodity hardware, computing, monitoring, deployment and source control systems. Lots of IT organizations still go through lot of manual process for provisioning, monitoring, analysis, setup and do not take advantage new age tools. We had these issues in our existing environment as well. WE have been managing our servers using new age configuration management tools but thats not sufficient as we did not bring that advantage to our end users.

2. About me
• Developer
• Sys Ad
• DevOps

3. More like a discussion
• Listen to our experiences
• Tell us about your experiences

4. About the talk

5. • Ruby for development
• Ruby for operations
• Used it for both - single team

6. Why Ruby?

7. • Nice language
• OpenSource
• DSLs can be built easily
• Great community
• Multiple implementations (JRuby, MRI etc)

8. Development

9. Build and testing

10. Provisioning

11. require 'fog'
fog = Fog::Compute.new(
:provider => 'AWS',
:region=>'eu-west-1',
:aws_access_key_id => 'yyy',
:aws_secret_access_key => 'xxxx'
)
server = fog.servers.create(
:image_id=>'ami-311f2b45',
:flavor_id=>'t1.micro',
:key_name => 'pey-pair-name'
)

12. Deployment

13. role :app, "A", "B"
role :web, "C"
task :deploy, :roles => :app do
run deploy
end

14. Configuration
Management

15. execute 'yum -y update -security'
package 'httpd'
service 'httpd' do
action :run
end
cookbook_file "/etc/httpd/conf.d/mysite.conf"
do
source "etc/httpd/conf.d/mysite.conf"
owner 'root'
group 'root'
mode '0644'
notifies :reload, 'service[httpd]'
end

16. pipe configuration with
provisioning

17. knife ec2 server create -r ‘role[web_server]’

mco rpc backup --with-fact ‘role=db’
mco rpc deploy --with-fact ‘role=app’
mco rpc chef --with-fact ‘role=loadbalancer’

25. Monitoring

26. {
"client": {
"name": "webapp01.local",
"address": "10.0.0.1",
"subscriptions": [ "web" ]
}
}

27. Supervising

28. Bluepill.application("httpd") do |app|
app.process("httpd") do |process|
process.start_command = "/usr/bin/
apachctl start"
process.pid_file = "/var/run/httpd.pid"
end
end

29. Ruby is ubiquitous
• Provisioning
• Configuration
• Development
• Continuous Integration
• Deployment
• Monitoring
